Description

  The present invention relates to a switch board with a base having a structure in which the on / off output changes when a slider slides on a switch pattern provided on the surface thereof, and a method of manufacturing the same.

  2. Description of the Related Art Conventionally, there is a switch board with a base for a rotary encoder that outputs a desired on / off waveform by rotating and sliding the slider. For example, as shown in FIG. 1 of Patent Document 1, this type of base-equipped switch board is insulated with a switch pattern provided on an insulating board made of synthetic resin film and a metal terminal attached to one end of the insulating board. A base made of molded resin is attached to the back surface of the substrate and its outer peripheral side. However, the conventional switch board with a base has the following problems.

  (1) In order to obtain an accurate output waveform from the switch board with the base, the sliding trajectory of the slider that is in sliding contact with each other on the switch pattern, in particular, on the edge surrounding the outer periphery of each switch pattern It is necessary to accurately form the edge of each crossing switch pattern. However, in the conventional switch board with a base, when the switch pattern is formed by screen printing a conductive paste, for example, the accuracy of the edge cannot always be improved.

  (2) Since the switch board with base supports the insulating substrate made of synthetic resin film only with the base made of molded resin, it cannot be said that the strength of the whole switch board with base is sufficiently strong. In particular, when the thickness of the base is reduced in response to a request for thinning the switch board with the base, there is a problem, and strengthening of the strength has been demanded.

(3) In order to prevent the intrusion of static electricity from entering the switch pattern of the switch board with the base from the outside, it is necessary to install a static intrusion prevention mechanism such as attaching a grounding plate for preventing static electricity separately. If it does so, a structure will become complicated and a manufacturing process will also become complicated.

It will be formed in an accurate and highly accurate position depending on the mold. Therefore, an accurate on / off waveform can be output.

  Next, FIG. 6 is a plan view of the reinforcing plate 60. The reinforcing plate 60 is made of a metal plate and has conductivity, and has an upper portion formed in a circular shape and a lower portion formed in a rectangular shape. That is, the flexible switch substrate 20 is formed to have substantially the same shape and dimension (except for the portion corresponding to the lower portion of the flexible switch substrate 20 where the terminal connection patterns 29, 31, 33 are provided). A circular shaft through hole 61 having a slightly larger size and shape is provided at a position facing the shaft insertion hole 35 of the substrate 20, and each of the positions facing the openings 45 of the flexible switch substrate 20 is slightly larger than these. A fan-shaped opening 63 having a dimensional shape is provided, and a circular positioning hole having a size slightly larger than these is provided at a position facing the pair of positioning holes 37 and 39 of the flexible switch substrate 20. 65 and 67 are provided. Further, a lightning protection portion 69 made of a tongue-like protrusion protruding outward is provided at the upper end portion of the reinforcing plate 60, and a pair of mounting portions 71, 71 protruding in a band shape from the left and right side portions of the reinforcing plate 60. Is provided. Note that the terminal plate 80 shown in FIGS. 1 to 3 is configured by forming a metal plate in a straight plate shape.

  Next, the base 90 will be described together with the entire structure of the base-equipped switch board 10 with reference to FIGS. 1 to 3. The base 90 is made of molded resin, and is formed so as to surround the outer periphery of the flexible switch substrate 20 and the base body 91 that is formed on substantially the entire bottom surface of the laminated flexible switch substrate 20 and the reinforcing plate 60. A side wall 93, a pressing portion 95 that holds the upper surface of the portion of the flexible switch substrate 20 to which the terminal plate 80 is attached, a shaft through hole 61 of the reinforcing plate 60 and the flexible switch substrate 20 from the central portion of the base body 91. And a circular columnar shaft portion 97 that projects through the shaft insertion hole 35 and protrudes upward from the flexible switch substrate 20. Further, columnar positioning portions 99 and 100 are projected from the upper and lower central portions of the lower surface of the base body 91, and the positioning holes 65 and 67 of the reinforcing plate 60 and the positioning holes 37 and 39 of the flexible switch substrate 20 are formed. The portions coincide with each other and penetrate vertically, and a circular concave portion 105 is provided at the center of the bottom surface of the base body portion 91 protruding from the shaft portion 97, and the concave portions 105 are also provided at five locations around the concave portion 105. 101, 103, 107, 109, 111 are provided. The recess 111 is formed in a region including the pair of positioning holes 65 and 67, and a recess 113 is also provided at a position corresponding to one end of the three terminal plates 80 below the recess 111. On the other hand, switch patterns 23 and 25 and a common pattern 27 are exposed on the upper surface of the flexible switch substrate 20. Further, from the outer periphery of the side wall portion 93, a lightning protection portion 69 and a pair of mounting portions 71, 71 provided on the reinforcing plate 60 protrude. Also, one end of each terminal plate 80 is sandwiched between the presser part 95 and the base body part 91 in the state where it is in contact with the terminal connection patterns 29, 31, 33 (see FIG. 4) of the flexible switch board 20, It is fixed. Four small protrusions 117 protrude from the upper end surface of the shaft portion 97.

  That is, the switch board with base 10 forms switch patterns 23 and 25 on which one of the following sliders 530 is slidably contacted on one surface of the film-like insulating substrate 21 and the sliders 530 of the switch patterns 23 and 25. A flexible switch substrate 20 formed with switch pattern end sides 23a, 23a, 25a, 25a by providing an opening 45 penetrating on the sliding contact locus L1 where the switch contacts, and the switch patterns 23, 25 of the flexible switch substrate 20 A reinforcing plate 60 that is provided in contact with the opposite surface provided with the opening 63 and that penetrates a portion of the flexible switch substrate 20 that faces the portion where the opening 45 is provided, and the reinforcing plate 60. Molded to hold the reinforcing plate 60 and the flexible switch board 20 around the flexible switch board 20 Further, the opening 45 of the flexible switch substrate 20 is filled through the opening 63 of the reinforcing plate 60, and the surface thereof is made to coincide with the height of the surfaces of the switch patterns 23 and 25 of the flexible switch substrate 20. The base 90 and the terminal connection patterns 29, 31, 33 provided on the flexible switch board 20 are abutted on one end, the other end protrudes to the outside of the base 90, and the upper and lower sides thereof are sandwiched and fixed by the base 90. And a terminal plate 80 formed as described above.

  Next, a method for manufacturing the switch board with base 10 will be described. To manufacture the switch board with base 10, first, the flexible switch board 20, the reinforcing plate 60, and the terminal plate 80 are prepared in advance. First, the reinforcing plate 60 is placed in contact with the opposite surface of the flexible switch board 20 on which the switch patterns 23 and 25 are provided.

  Then, the laminated flexible switch board 20, the reinforcing plate 60, and the terminal plate 80 are installed and held in molds (first mold and second mold) 200, 300 as shown in FIG. Fix it. At this time, by inserting the pins provided in any of the molds 200 and 300 into the pair of positioning holes 37 and 39 of the flexible switch substrate 20 and the pair of positioning holes 65 and 67 of the reinforcing plate 60, the positions of the two match. Therefore, at the same time, the shaft insertion hole 35 and each opening 45 of the flexible switch substrate 20 accurately face the shaft through hole 61 and each opening 63 of the reinforcing plate 60, respectively. At this time, the formation surfaces of the switch patterns 23 and 25 of the flexible switch substrate 20 are brought into surface contact with the mold surface (specifically, the substrate abutting surface 201 of the first mold 200) and simultaneously provided on the second mold 300. The flexible switch substrate 20 and the reinforcing plate 60 are sandwiched by bringing the surfaces of the five protruding portions 301 (only one portion shown in FIG. 7) into contact with the lower surface of the reinforcing plate 60. At the same time, the same cavity C1 as the outer shape of the base 90 is formed around the flexible switch substrate 20 and the reinforcing plate 60. Further, at the same time, the terminal plate 80 is also in contact with the terminal connection patterns 29, 31, 33 of the flexible switch substrate 20 with one end thereof in contact with the substrate contact surface 201 of the first mold 200 and the second mold 300. Are clamped and fixed by the protrusions 303 provided in (in fact, there are three for each terminal board 80). The protrusions 301 are provided at four locations other than the positions shown in FIG. 7, and the protrusions 301 form the recesses 101, 103, 107, 109, 111 shown in FIG. Further, the three protrusions 303 form the three recesses 113 shown in FIG.

  Then, molten resin is injected (press-fitted) from the resin injection port G provided at the lower end of the cavity C1 of the second mold 300 which becomes the positioning portion 100 shown in FIG. All are filled with this melt-molded resin. At the same time, the molding resin is filled into the opening 45 of the flexible switch substrate 20 through the opening 63 of the reinforcing plate 60. Then, if the first and second molds 200 and 300 are removed after the molding resin is solidified, the reinforcing plate 60, the flexible switch substrate 20, and the terminal plate 80 are attached to the base 90 made of the molding resin. 3 can be taken out.

  The base-equipped switch board 10 manufactured as described above is provided with a base 90 made of molded resin after the reinforcing plate 60 is laminated and installed on the lower surface of the flexible switch board 20. The strength of the entire switch substrate 10 can be sufficiently increased by the reinforcing plate 60. Therefore, sufficient strength can be maintained even if the thickness of the base-equipped switch board 10 including the base 90 is reduced to reduce the thickness thereof.

  Further, since the reinforcing plate 60 is made of a metal plate and has conductivity, it also serves as a ground plate. In particular, the lightning protection portion 69 and the pair of attachment portions 71 protrude from the outer periphery of the base portion 90 toward the outside thereof, so that the static electricity enters the inside of the switch substrate 10 with the base before the outside of the switch substrate 10 with the base. Incident in these parts. Accordingly, it is possible to reliably prevent static electricity from entering the conductor patterns such as the switch patterns 23 and 25. Since the reinforcing plate 60 also functions to prevent static electricity intrusion, there is no need to separately attach a grounding plate for preventing static electricity intrusion, and the structure is simple and manufacture is easy. Further, the reinforcing plate 60 also serves as an attachment function for attaching the switch board 10 with a base to another fixed side member by the pair of attachment portions 71.

  Further, in this switch board 10 with a base, the molding resin constituting the base 90 is filled in the opening 45 of the flexible switch board 20 and the surface thereof is set to the height of the surfaces of the switch patterns 23 and 25 of the flexible switch board 20. Since they are matched with each other, the sliding booklet 533 (see FIG. 9) of the slider 530 described below can move smoothly on that (on the sliding contact locus L1). The switch board 10 with a base is provided with a reinforcing plate 60 on the lower surface side of the flexible switch board 20. Since the opening 63 is provided in the reinforcing plate 60, a base 90 on the lower side is configured. The molding resin and the opening 45 provided in the flexible switch substrate 20 can communicate with each other, and the molding resin can be easily filled in the opening 45 of the flexible switch substrate 20. By the way, as described above, the opening 63 is formed to have a slightly larger size and shape than the opening 45, for the following reason. Here, FIG. 10 is a diagram showing the positional relationship between the opening 45 and the opening 63, and FIG. 10A is an enlarged plan view of the main part of one opening 45 portion in which the switch pattern edge 25a is formed, and FIG. ) Is a cross-sectional view taken along line FF in FIG. 10A, and FIG. 10C is a cross-sectional view taken along line FF in FIG. 10A in a state in which the base 90 is formed in the opening 45 and the opening 63. As shown in the figure, the opening 63 is formed in a size slightly larger than the opening 45 so that at least the switch pattern edge 25 a of the flexible switch substrate 20 is positioned inside the opening 63 of the reinforcing plate 60. It is configured. This is because when the opening 45 is formed by mechanical cutting or the like, as shown in FIGS. 10B and 10C, the portion of the switch pattern edge 25a may sag inside the opening 45. In such a case, if the conductive reinforcing plate 60 is located in the vicinity, there is a possibility that a short circuit or the like may occur between the two. Therefore, in order to surely prevent such a fear, the opening 63 is formed to have a slightly larger dimension than the opening 45. Since at least the switch pattern edge 25a of the flexible switch substrate 20 does not have to be close to the reinforcing plate 60, it is not always necessary to form the entire opening 63 in a size larger than the opening 45, and the switch pattern of the opening 63 is not necessarily formed. Only the vicinity of the edge 25a may be separated from the switch pattern edge 25a. In other words, at least the switch pattern edge 25a may be configured to be located inside the opening 63 of the reinforcing plate 60. Of course, when such a problem does not occur, the size of the opening 63 and the opening 45 may be the same, or conversely, the opening 63 may be formed smaller than the opening 45 as described below. .

  That is, various changes can be made in the shape and number of the openings 63 provided in the reinforcing plate 60. Since the opening 63 is for guiding the molding resin constituting the base 90 to the opening 45, for example, as shown in FIG. Alternatively, as shown in FIG. 8B, an opening 63 having an outer dimension smaller than the opening 45 may be used. In short, any shape may be used as long as the opening 63 has a shape capable of guiding the molding resin constituting the base 90 to each opening 45. In the embodiment shown in FIG. 6, the openings 63 of the reinforcing plate 60 are provided for each of the openings 45 of the plurality of flexible switch boards 20, as shown in FIG. This is because if one opening 63 is provided, the strength of the reinforcing plate 60 is reduced accordingly. That is, in the embodiment shown in FIG. 6, the strength of the reinforcing plate 60 is strongly maintained by providing the opening 63 for each opening 45.

  FIG. 9 is a schematic cross-sectional view of the rotary switch 500 assembled using the switch board with base 10 manufactured as described above. As shown in the figure, the rotary switch 500 includes a switch board 10 with a base, a molded resin sliding knob combined with a slider 530 attached to the lower surface thereof, and a sliding knob combined with a sliding mold. A click mechanism 550 installed in a click mechanism storage 515 provided on the upper surface of the rotary knob 510 is provided. In addition, each terminal board 80 and the mounting part 71 of the switch board 10 with a base are bent at right angles to the lower surface side of the base 90 at a position protruding to the outside of the base 90, and a board or an exterior installed below the base board 90 It is fixed to a fixed member 600 such as a case. At this time, each terminal board 80 is electrically connected to the circuit of the stationary member 600, and the mounting portion 71 is electrically connected to the ground member of the stationary member 600. The positioning members 99 and 100 of the base-equipped switch board 10 are inserted into a hole (not shown) provided in the fixed member 600 and positioned. On the other hand, the sliding object / rotary knob 510 is provided on a substantially disk-shaped sliding part 511, a knob part 513 provided around the sliding part 511, and an upper part of the sliding part 511. The click mechanism accommodating portion 515 is provided, and a shaft support hole 517 is provided in the center of the sliding-type object portion 511 so as to pass through the shaft portion 97 of the switch board with base 10 so as to be rotatable. The slider 530 is made of an elastic metal plate, and is fixed to the lower surface of the sliding type object / rotary knob 510, and slides from the base portion 531 to the switch patterns 23 and 25 and the common pattern 27 of the flexible switch substrate 20. A sliding booklet 533 to be brought into contact is projected. The click mechanism 550 includes a click plate 560 that is fixed to the bottom surface of the click mechanism storage portion 515, and a substantially disc-shaped presser made of synthetic resin that is fixed to the upper portion of the shaft portion 97 and has a click spring 580 fixed to the lower surface thereof. And a member 570. The click plate 560 is a ring-shaped flat plate (metal plate) and has openings 561 provided at equal intervals. A fitting portion 571 for fitting the small protrusion 117 at the upper end of the shaft portion 97 is provided in the center of the pressing member 570. The click spring 580 is made of an elastic metal plate, and a part of the ring-shaped base part 581 is bent downward in an arc shape to form a resilient arm part 583, and a resilient part (not shown) is formed at the center thereof. It is provided and configured. Then, the shaft part 97 of the switch board 10 with the base is rotatably inserted into the shaft support hole 517 of the rotary knob 510 having the sliding type object to which the slider 530 and the click plate 560 are attached. When the small protrusion 117 is inserted into the fitting portion 571 of the holding member 570 to which the click spring 580 is attached and the tip of the small protrusion 117 is caulked, the rotary switch 500 is completed. Then, if the outer periphery of the rotary knob 510 which is also a sliding type object is rotated by a finger or the like, the sliding booklet 533 of the slider 530 is brought into sliding contact with the switch contact patterns 23 and 25 on the common pattern 27, and between the terminal boards 80. The on / off output changes. At this time, as described above, the switch pattern end sides 23a, 23a, 25a, and 25a of the switch contact patterns 23 and 25 are formed with high accuracy, so that the ON / OFF waveform also has a desired high accuracy output. On the other hand, when the sliding-type object / rotary knob 510 is rotated, the elastic portion of the click spring 580 engages and disengages from the opening 561 of the click plate 560, and a click feeling is generated. In the rotary switch 500, the pressing member 570 is attached to the shaft portion 97, and the click spring 580 is attached to the surface of the pressing member 570 facing the sliding type object portion 511. Therefore, the click spring 580 can be reliably protected from the outside (the upper surface side of the rotary knob 510 that also serves as a sliding-type object). In addition, since the entire click spring 580 can be firmly supported, a good click feeling can be obtained.

  By the way, the shape of the fixed side member 600 shown in FIG. 9 is formed such that the position for driving the sliding-type object / rotary knob 510 is one position (the position of the point B). Accordingly, the charged finger or the like rotates the sliding object / rotary knob 510 at this position B. When the finger or the like is charged, the static electricity falls to the lightning protection portion 69 located near the finger or the like and is grounded. That is, it is possible to prevent static electricity from entering the circuit pattern on the switch board 10 with base.
